Predicting the Weight of Holstein-Friesian Males at Different Ages by some Body Measurements

This study was conducted in one of the private fields for breeding Holstein-Friesian calves in the village of Al-Hamad in Al-Diwaniyah Governorate, where 107 males were used, including 21 at the age of 1 year, 51 at the age of 2 years, and 35 at the age of 3 years. The animals were weighed with an e...

Zusammenfassung:This study was conducted in one of the private fields for breeding Holstein-Friesian calves in the village of Al-Hamad in Al-Diwaniyah Governorate, where 107 males were used, including 21 at the age of 1 year, 51 at the age of 2 years, and 35 at the age of 3 years. The animals were weighed with an electronic scale, and body measurements (height body, chest girth and hip girth in centimeters) and the study aims to find the best single or double size to estimate the body weight of Holstein Friesian males, and the results of the current study can be summarized as follows: It was found that age had a highly significant effect (p
